Rooster comb rounded

[PrairiePeckers]

I have a 1 y/o RIR roo, his comb tips have always came to a point. They are now rounded. What does this mean??

Looks like the work of frostbite. Were the tips ever purple, or black, or any other sort of discolouration?

Yes you can see in the first photo he had a bit beginning. I had heck getting him to go into the coop when we had a cold spell.
